A nurse is examining the urine output of a client with Parkinson’s disease who is on the medication Levodopa. Which of the following is a common observation for a client on this medication?

Choice A rationale:
Reduced kidney ability to concentrate urine is a common physiological change associated with normal aging. This is due to several factors, including:

Decreased glomerular filtration rate (GFR): The kidneys filter waste products from the blood. As we age, the number of functioning nephrons (filtering units) in the kidneys decreases, leading to a decline in GFR. This means that the kidneys are less able to filter waste products and concentrate urine.
Decreased renal blood flow: Blood flow to the kidneys also decreases with age. This further reduces the kidneys' ability to filter waste products and concentrate urine.
Decreased tubular function: The tubules in the kidneys are responsible for reabsorbing water and electrolytes from the urine. As we age, the function of the tubules also declines, leading to a decrease in the ability to concentrate urine.
As a result of these changes, older adults often produce more urine, even at night. This can lead to nocturia, which is the need to wake up to urinate two or more times per night.
Choice B rationale:
Lower fluid intake during daytime hours can also contribute to nocturia, but it is not a direct physiological change associated with normal aging. Older adults may drink less fluids during the day for a variety of reasons, such as decreased thirst sensation, fear of incontinence, or limited access to fluids. However, even if they maintain adequate fluid intake during the day, they may still experience nocturia due to the reduced ability of their kidneys to concentrate urine.
Choice C rationale:
Enhanced bladder contractility leading to urinary stasis is not a typical physiological change associated with normal aging. In fact, bladder contractility often decreases with age, which can lead to difficulty emptying the bladder completely. This can contribute to urinary frequency and urgency, but it is not typically a cause of nocturia.
Choice D rationale:
Increased bladder muscle tone leading to frequent urination is also not a typical physiological change associated with normal aging. Bladder muscle tone may decrease with age, which can lead to difficulty emptying the bladder completely. However, it is not typically a cause of nocturia.

Choice A rationale:
Tertiary health promotion and illness prevention focus on managing existing health conditions and preventing complications. Administering a nebulized bronchodilator to a client who is short of breath directly addresses an existing respiratory problem, aiming to relieve symptoms and prevent further respiratory distress. This intervention falls under tertiary prevention because it targets a client already experiencing respiratory symptoms.
Key points:
Bronchodilators open constricted airways, easing airflow and breathing.
Nebulizers deliver medication directly to the lungs, providing rapid relief.
Shortness of breath is a common symptom of respiratory conditions like asthma and COPD.
Prompt treatment of respiratory symptoms can prevent worsening of the condition and potential complications.
Choice B rationale:
Teaching a client about the risks of light cigarettes is an example of primary prevention. It aims to prevent lung disease before it develops by educating individuals about the harms of smoking.
Choice C rationale:
Advocating for more explicit warning labels on cigarette packages is a form of secondary prevention. It targets at-risk populations (smokers) to encourage behavior change and reduce smoking rates, ultimately lowering the incidence of lung disease.
Choice D rationale:
Assisting with lung function testing is a diagnostic procedure, not a tertiary prevention intervention. It helps to identify respiratory problems but doesn't directly manage or prevent them.
